This 3 18" Fan Mist Cooling Kit with 1000 PSI Pump high pressure misting fans provide optimal cooling for open spaces such as backyard patios or restaurant dining areas. Fans help disperse the fine mist droplets throughout a larger area without getting objects wet. Some customers also use our misting fans to humidify warehouses, cool horse/dairy barns, and lower the ambient temperature for patrons waiting in lines at theme parks.
